The invention provides a valve rod and a tire valve which can connect circuits with each other even when a valve cover is detached. The valve rod (10) has a tubular structure, is fixed in a state of penetrating through a valve mounting hole (81H) of a tire wheel (80), and accommodates a valve body (20), and the valve rod (10) is provided with: a pair of internal electrodes (11N, 31N) connected to an internal circuit (91) in a tire (82); a pair of external electrodes (11G, 31G) which are disposed on the outer peripheral surface of a tire outer protrusion (17) protruding outside the tire (82) in the valve stem (10) and which can be connected to an external circuit (96) outside the tire (82); and first and second conductive members (11, 31) that have internal electrodes (11N, 31N) and external electrodes (11G, 31G) and are insulated from each other.
本发明提供即使在卸下了阀盖的期间也能够进行电路彼此的连接的阀杆以及轮胎阀。阀杆(10)呈管状构造,以贯穿胎轮(80)的阀装配孔(81H)的状态固定,并收容阀芯(20),该阀杆(10)具备:一对内部电极(11N、31N),它们与轮胎(82)内的内部电路(91)连接;一对外部电极(11G、31G),它们配置于阀杆(10)中的向轮胎(82)外突出的轮胎外突出部(17)的外周面,并能够与轮胎(82)外的外部电路(96)连接;以及第一导电构件与第二导电构件(11、31),它们具有内部电极(11N、31N)与外部电极(11G、31G)并相互绝缘。
